First described in 1991 and introduced into clinical practice in 1996, optical coherence tomography (OCT) now has a very extensive role in many different areas of ophthalmological practice. It is non-invasive, cheap, highly reproducible, widely available and easy to perform. OCT also has a role in managing patients with neurological disorders, particularly idiopathic intracranial hypertension. This review provides an overview of the technology underlying OCT and the information it can provide that is relevant to the practising neurologist. Particular conditions discussed include papilloedema, optic disc drusen, multiple sclerosis and neuromyelitis optica, other optic neuropathies, compression of the anterior visual pathway and various neurodegenerative conditions.

光学相干断层扫描：通往大脑的窗口？

光学相干断层扫描 (OCT) 于 1991 年首次描述并于 1996 年引入临床实践，现在在眼科实践的许多不同领域具有非常广泛的作用。它是非侵入性的、便宜的、高度可重复的、广泛可用且易于执行的。OCT 还可用于管理神经系统疾病患者，尤其是特发性颅内高压患者。本综述概述了 OCT 的基础技术及其可以提供的与执业神经科医生相关的信息。讨论的特定病症包括视乳头水肿、视盘玻璃疣、多发性硬化症和视神经脊髓炎、其他视神经病变、前视觉通路受压和各种神经退行性疾病。
